Improvement in hat-pressing machines



UNITED STATES PATENT OEEroEK ISAAC T. GREEN, OF MILFORD, CONNECTICUT,ASSIGNOR TO HIMSELF AND C. H. BERRY, OF FORT GREEN PLACE, BROOKLYN,NEINT YORK.

IMPROVEMENT IN HAT-PRESSING MACHINES.

Specification forming part of Letters Patent No. 58,5114, datcd October2, 1866.

To all whom it may concern:

Be it known that I, ISAAC T. GREEN, of Milford, New Haven county, Stateot' Connecticut, have invented a new and useful Improvenient inPressingHats; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure lrepresents a vertical central section of this invention. Fig. 2 is ahorizontal section of the same, the line Fig. l, indicating-the plane ofsection.

Similar letters of reference indicate like parts.

This invention consists in the application of steam to the hat while thesame is in place between the presser and the die, in such a manner thatby the action of the steam the material from which the hat is made iskept soft and pliable, and said hat assumes the correct shape.

It consists, also, in the employment or use of a wet sheet incombination with the presser and die, in such a manner that by theaction of the heated presser on the wet sheet the moisture from saidsheet is expelled in the form of steam, and the material from which thehat is made is kept soft and pliable while being pressed.

It consists, further, in the use of a perforated shield in combin ationwith the wet sheet, the presser, and die, in such a manner that thesteam formed by the action of the presser on the wet sheet is brought inuniform contact with the hat, the steam being allowed to pass throughthe perforated shield without obstruction.

It consists, further, in'makin g the perforated shield thicker at thebottom than at the top, so that by introducing the presser the requisitepressure at the sides is obtained, said presser being made wedge-shapedto facilitate its introduction into the shield.

A represents the die, and B the presser, which are both made of iron orother suitable material, in the proper form and shape to correspond tothe shape of the hats to be pressed.

The die is so arranged that it.ean be heated with steam or hot air, andafter the hat to be pressed has been adjusted in the same I iii--troduce a perforated shield, C, which is made tapering, being thicker atthe bottom than at thetop, so that when the presser B is introduced auniform pressure toward all sides is effected. The presser B is alsomade tapering or wedge-shaped, as shown in Fig. l of the drawings, sothat it can be readily introduced in the shield and that its shapecorresponds to that of said shield.

While the operation of pressing is going on, or while the hat is betweenthe presser and the die, I introduce ajet of steam; or, instead of this,I apply a wet sheet, D, between the presser and perforated shield. y

The presser, being heated, transforms the moisture contained in the wetsheet into steam as the operation of pressing progresses, and therequisite amount of steam is generated to keep the material from whichthe hat is made soft and pliable. The steam thus generated passesreadily through the perforated shield.

3y these means I am enabled to press a hat with ease and facility, andto give it the proper form or sha-pe without trouble or loss otl time.

W/hat I claim as new, and desire to secure by Letters Patent, is-

l. The application of steam to the hat while the same is in placebetween the presser' and the die, as and for the purpose described.

2. The employment of a wet sheet, in combination with the die andpresser, while the operation of pressing a hat progresses, substantiallyas and for the purpose set' forth.

3. The perforated shield C, in combination with the presser and die,substantially as and for the purpose described. Y

4. The perforated shield C and wet sheet D, in combination with thepresser and die, as set forth.

5. Making the perforated shield tapering or thicker at the bottom, asand for the purpose described.

The above specification of my invention signed by me this 24th day ofMarch, 1866..
